Bih Hycenta Chendi, Tracey Jooste, Thomas Jens Scriba, Martin Kidd, Simon Mendelsohn, Kristian Tonby, Gerhard Walzl, Anne M. Dyrhol-Riise & Novel Njweipi Chegou
Host transcriptomic blood signatures have demonstrated diagnostic potential for tuberculosis (TB), requiring further validation across different geographical settings. Discriminating TB from other diseases with similar clinical manifestations is crucial for the development of an accurate immunodiagnostic tool. In this exploratory cohort study, we evaluated the performance of potential blood-based transcriptomic signatures in distinguishing TB disease from non-TB lower respiratory tract infections in hospitalised patients in a TB low-endemic country. Quantitative real-time polymerase chain reaction qPCR)...

Erickson
Abstract Background Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease that can lead to cirrhosis and hepatic decompensation. However, predicting future outcomes in patients with PSC is challenging. Our aim was to extract magnetic resonance imaging (MRI) features that predict the development of hepatic decompensation by applying algebraic topology-based machine learning (ML). Methods We conducted a retrospective multicenter study among adults with large duct PSC who underwent MRI. A topological data analysis-inspired nonlinear...

Trauma-related altered states of consciousness in post-traumatic stress disorder patients with or without comorbid dissociative disorders

Harald Bækkelund, Paul Frewen, Ruth Lanius, Akiah Ottesen Berg & Espen Ajo Arnevik
Background: The four-dimensional (‘4-D’) model has been proposed as a theoretical framework to understand and delineate trauma-related dissociative experiences, categorizing symptoms into trauma-related altered states of consciousness (TRASC) and normal waking consciousness (NWC), which occur along four dimensions: time, thought, body and emotion. Objective: The main aim of the present study was to evaluate the validity of this model in patients with post-traumatic stress disorder (PTSD), with and without comorbid dissociative disorders. Method: The predictions...

Cancers require telomere maintenance mechanisms for unlimited replicative potential. They achieve this through TERT activation or alternative telomere lengthening associated with ATRX or DAXX loss. Here, as part of the ICGC/TCGA Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium, we dissect whole-genome sequencing data of over 2500 matched tumor-control samples from 36 different tumor types aggregated within the ICGC/TCGA Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium to characterize the genomic footprints of these mechanisms. While the...

Data from: Apolipoprotein (ApoE) polymorphism is related to differences in potential fertility in women: a case of antagonistic pleiotropy?

Grazyna Jasienska, Peter T. Ellison, Andrzej Galbarczyk, Michal Jasienski, Malgorzata Kalemba-Drozdz, Maria Kapiszewska, Ilona Nenko, Inger Thune & Anna Ziomkiewicz
The alleles that are detrimental to health, especially in older age, are thought to persist in populations because they also confer some benefits for individuals (through antagonistic pleiotropy). The ApoE4 allele at the ApoE locus, encoding apolipoprotein E (ApoE), significantly increases risk of poor health, and yet it is present in many populations at relatively high frequencies. Why has it not been replaced by natural selection with the health-beneficial ApoE3 allele? ApoE is a major...

Data from: Getting to the heart of emotion regulation in youth: the role of interoceptive sensitivity, heart rate variability, and parental psychopathology

Nele A. J. De Witte, Stefan Sütterlin, Caroline Braet & Sven C. Mueller
Emotion regulation and associated autonomic activation develop throughout childhood and adolescence under the influence of the family environment. Specifically, physiological indicators of autonomic nervous system activity such as interoceptive sensitivity and vagally mediated heart rate variability (HRV) can inform on emotion regulation. Although the effect of parental emotion socialization on emotion regulation appears to be influenced by autonomic processes, research on physiological regulation and the influence of parental factors remains scarce. This study investigated the...

Data from: Persistent low toxoplasma IgG avidity is common in pregnancy: experience from antenatal testing in Norway

Gry Findal, Babill Stray-Pedersen, Ellen K. Holter, Tone Berge & Pål A. Jenum
The parasite Toxoplasma gondii might harm the fetus if a woman is infected during pregnancy. IgG seroconversion and significant increase in IgG antibody amount in pregnancy indicates maternal infection. Presence of toxoplasma immunoglobulin M (IgM), immunoglobulin G (IgG) and low IgG avidity in a single serum sample indicates possible maternal infection, but positive toxoplasma IgM and low IgG avidity may persist for months and even years. We aimed to evaluate avidity development during pregnancy in...

An electrophysiological marker of arousal level in humans

Janna Lendner, Randolph Helfrich, Bryce Mander, Luis Romundstad, Jack Lin, Matthew Walker, Pal Larsson & Robert Knight
Deep non-rapid eye movement sleep (NREM) and general anesthesia with propofol are prominent states of reduced arousal linked to the occurrence of synchronized oscillations in the electroencephalogram (EEG). Although rapid eye movement (REM) sleep is also associated with diminished arousal levels, it is characterized by a desynchronized, 'wake-like' EEG. This observation implies that reduced arousal states are not necessarily only defined by synchronous oscillatory activity. Using intracranial and surface EEG recordings in four independent data...

Criteria for defining interictal epileptiform discharges in EEG: a clinical validation study

Mustafa Aykut Kural, Lene Duez, Vibeke Sejer Hansen, Pål Gunnar Larsson, Stefan Rampp, Reinhard Schulz, Hatice Tankisi, Richard Wennberg, Bo Bibby, Michael Scherg & Sandor Beniczky
Objective: To define and validate criteria for accurate identification of EEG interictal epileptiform discharges (IEDs) using: (a) the six sensor space criteria proposed by the International Federation of Clinical Neurophysiology (IFCN), and, (b) a novel source space method. Criteria yielding high specificity are needed because EEG “over-reading” is a common cause of epilepsy misdiagnosis. Methods: Seven raters reviewed EEG segments containing sharp waveforms from 100 patients with and without epilepsy. Clinical diagnosis gold standard was...

A progressive three-state model to estimate time to cancer: a likelihood-based approach

Eddymurphy U. Akwiwu, Thomas Klausch, Henriette C. Jodal, Beatriz Carvalho, Magnus Løberg, Mette Kalager, Johannes Berkhof & Veerle M.H. Coupé
Abstract Background To optimize colorectal cancer (CRC) screening and surveillance, information regarding the time-dependent risk of advanced adenomas (AA) to develop into CRC is crucial. However, since AA are removed after diagnosis, the time from AA to CRC cannot be observed in an ethically acceptable manner. We propose a statistical method to indirectly infer this time in a progressive three-state disease model using surveillance data. Methods Sixteen models were specified, with and without covariates. Parameters...

Exercise-induced change in circulating NT-proBNP could not distinguish between patients with and without coronary artery disease: the CADENCE study

Joanna Cwikiel, Morten W. Fagerland, Kristian Wachtell, Harald Arnesen, Ingebjørg Seljeflot & Arnljot Flaa
Objective. In patients with chest pain, exercise stress test has a moderate accuracy for coronary artery disease (CAD). Adding a reliable cardiac biomarker to the exercise test could potentially improve the precision of the test. We investigated circulating NT-proBNP levels before and during exercise stress test in patients with and without angiographically verified CAD. We hypothesized that NT-proBNP would give an additive diagnostic value to the exercise stress test. Methods. In patients presenting with symptoms...

Adipose-derived stromal cells preserve pancreatic islet function in a transplantable 3D bioprinted scaffold

Shadab Abadpour
Intra-portal islet transplantation is the method of choice for treatment of insulin dependent type 1 diabetes, but its outcome is hindered by limited islet survival due to the immunological and metabolic stress post transplantation. Adipose-derived stromal cells (ASCs) promise to improve significantly the islet micro-environment but an efficient long-term delivery method has not been achieved. We therefore explore the potential of generating ASC enriched islet transplant structure by 3D bioprinting. Here, we fabricate a double-layered...
